【摘要】 对3种新型杀菌剂进行室内毒力测定结果表明,阿米西达对晚疫病菌菌丝生长的抑制效果最佳,EC50为0.0623μg/mL。氟吗·锰锌和氟吗·锰锌+克露的田间防治效果均达到90%以上,其它2种单剂和1种混剂田间防治效果在64.3%～83.6%。各处理均有增产作用,其中阿米西达增产效果最显著,达到21.8%。更多还原

【Abstract】 The results of indoor toxicity measurement of three new fungicides showed that Azoxystrobin had the best control effect in inhibiting mycelia growth,its EC50 was 0.0623μg/mL.The control effects of flumorph· mancozeb and flumorph·mancozeb+curzate treatments against Phytophthora infestans in field were all more than 90% and the control effect of other two simple and mixture fungicides in field was during 64.9%～ 83.8%.All the treatments could increase production in this study.Among them,Azoxystrobin had the prominent increasing production,up to 21.8%.更多还原
